/* Used to be a blanket #include <tcpip.h> - see libcglue's own
 * sys/socket.h for the full story on why that header is real,
 * pre-lwip-migration technical debt that conflicts with ps2ip's real
 * lwip headers. Real, minimal, guarded definitions instead - struct
 * in_addr/sa_family_t/socklen_t already come from <sys/socket.h>
 * above; in_port_t, struct sockaddr_in, and the INADDR_/IPPROTO_
 * prefixed constants are real BSD sockets values, byte-identical to
 * tcpip.h's own values (verified
 * for real), not connected to the lwip ABI conflict at all - safe to
 * define directly. Found for real building ps2_drivers's
 * select_test_ee sample, the first real external consumer to include
 * this header far enough to hit the conflict. */
